Per View from the Wing:
Frugal Travel Guy points to a British Midland bonus for Hertz rentals.
Hertz rentals booked here using Promotional Coupon 123631 from 20 August through 30 September 2008 earn 3400 bmi miles rather than the standard 1700 (which is easily the best standard offer to start with).
That’s a great deal! Maybe not worthy of renting just for the miles, but if you have to rent, this is a mighty fine offer.
